Smith, 66, was found when Lenawee County Sheriff's Deputies responded to a welfare check at his home, 11818 Silver Lake Highway, at 7:34 p.m. Sunday, July 20.

"This is not a random incident," a news release from the Lenawee County Sheriff's Office said. "We believe the victim was probably familiar with the subject. At least one person of interest is being investigated."

No suspects have been arrested in relation to Smith's death.

Friends and family gathered at Smith's home Monday declined to comment.

Police said the exact time of Smith's death is unknown but appeared to be recent. An autopsy has been scheduled.

The investigation is ongoing.
